Detector Loop Sealant

Q-Seal 290S is available in black and gray formulations, allowing contractors to closely match the sealant color to the surrounding concrete or asphalt surface. This helps maintain a clean, uniform pavement appearance while still providing full protection for the underlying detector loop wiring.

The sealant is dispensed directly into saw cuts using a manual applicator gun, filling the groove around the installed detector wire loop. It cures to form a tough, flexible protective layer that bonds to both concrete and asphalt, sealing out moisture and debris while allowing for normal traffic loading.

Q-Seal 290S is sold in case packs of 12 tubes, with each tube containing 30 fluid ounces of sealant. This case quantity is designed for contractor efficiency on municipal traffic signal installation and maintenance projects, minimizing reorder frequency for larger jobs.

Yes, Q-Seal 290S is formulated for use in saw cuts made in both concrete and asphalt roadway surfaces. Its moisture-cure chemistry allows it to bond effectively to either substrate, making it versatile for a wide range of intersection and roadway installation conditions.

A manual applicator gun, such as the compatible Avon-style gun used with the Ply Pak variant, is recommended for controlled, consistent dispensing into the saw cut. This equipment helps contractors achieve an even fill around the detector wire loop without excess waste.

Detector loop sealant is suitable for both new vehicle detection loop installations and ongoing signal maintenance work. Whether cutting fresh loops into new pavement or resealing loops during intersection upkeep, the sealant provides consistent protection for the embedded detector wiring.
